MAC it happen : Presented is a study of the synergistic structuredirecting effect of metal–amine complexes (MACs) with different chelating polyamine ligands and imidazolium-based ionic liquid (IL) cations. For the first time, a layered selenidostannate with an asymmetric eight-membered ring, an organic-decorated layered selenidostannate, and a 3D selenidostannate with both the MAC and IL cation...

Coenzyme B6 dependent novel bond cleavage reactions

Coenzyme B6 is an important cofactor participating in many diverse biotransformations. W e the function of this coenzyme in enzyme catalysis has been well established, recent studies have led to two novel coenzyme B6-dependent reactions whose catalyses involve unique mechanistic variants of usual coenzyme B6 chemistry. These are a C 0 bond cleavage and a C-C bond cleavage reaction catalyzed by ...

Stille coupling via C–N bond cleavage

Cross-coupling is a fundamental reaction in the synthesis of functional molecules, and has been widely applied, for example, to phenols, anilines, alcohols, amines and their derivatives. Here we report the Ni-catalysed Stille cross-coupling reaction of quaternary ammonium salts via C-N bond cleavage. Aryl/alkyl-trimethylammonium salts [Ar/R-NMe3]+ react smoothly with arylstannanes in 1:1 molar ...

A Facile and Environmental Friendly Method for C=N Bond Cleavage of Imines Using p-Toluenesulfonic Acid in Solid State

A simple, efficient and clean procedure has been developed for the cleavage of imines C=N bond. Deprotection of imines to their parent carbonyl and amine compounds was achieved using p-toluenesulfonic acid in the solid state condition at 25-45 ˚C. The salient features of this methodology are shorter reaction times, cheap processing, high yields of product and easy availability of the catalyst. ...
